LOOM-JACQUARD.

SPECIFICATION formngpart of Letters Patent No. 711,499, dated October-21, 190,2.

Application filed October 17, 1901. Serial No. 78,909.' (No model.)v

To @ZZ whom it may concern,.-

Beit known that I, GsTAvE HOVE, designer, a citizen of the French Republic, residing at 105 Falls road, Belfast, Ireland, have invented certain new and useful Improvements in Loom-Jacquards, of which the following is a specification.

This invention relates to a method of obtaining on common harness or twilling .Iacquard power and hand looms the satins in the figures or designs running in a reverse way to the satins in the ground' and also to the binding of the figures on each vertical and horizontal side, so as to make aperfect cloth.

Theinvention applies to satins of five and its derivatives-seven,ieight, nine, ten, twelve, dacand alsocomposites such as five in the ground and-eight or ten in the figure, to satins in ground and diagonals'in figures, and vice versa, to diagonals in ground and diagonals in figures, and, infact, to all armures or bindings used in damask fabrics.

In order that the invention may be properly understood, I have hereunto appended drawings, whereon- Figure 1 shows in side view part of the jacquard mechanism of an ordinary twillingloom of the well-known Bessbrook pattern and as altered in accordance with my invention. Fig. 2 is a part plan view of the mechanism. Fig. 3 is a view of a special hook used by me. Fig. 4 is a diagrammatic sketch plan drawn with a view of illustrating my invention clearly. It shows a few griff-knives and twilling-barswith a few hooks. Figs. 5, 6, 7, 8,9, 10, and 11 are diagrams explaining the method of working my invention.

In Figs. 1 andv2, a represents the card-cylinder; b, thecards; c, the needle-frame; d, the needles;` f, the ordinary rows of vertical hooks; g, the spring-box; h, the perforated board; i, the griff-frame; j, the ordinary movable griff knives or blades; k to 7c5, the ordinary twilling-bars; l, the pins on the bars for moving the knives;` m, the peg-cylinder; m' to 'm5, pegs on the cylinder; fn, the ordinary long lifting-hooks of the Bessbrook machine, and o the catches on the twilling-bars for lifting these hooks.

Sufficient only has beenshown on the drawings to enable one skilled in the. art of weavteen hundred hooks in all.. .4

A quadruple scale has four hooks to each needle and forty rows ofv fifty hooks, or two thousand hooks `in all, and so on. v y

In the five-satin or four and one satin double-scale machine represented at Figs. l and 2 there are ten rows of needles (with twenty hooks in each'row) and twenty rows of hooks, (with iifty in each row.)

Under my invention I fitin the griff-frame of the machine a special knife j midway between the ordinary third and fourth knives, a special knife ,72 between the eighth and ninth knives, a special knife js between the thirteenth and fourteenth, and a special knife j4 between the .eighteenth and nineteenth. These knives are made and arranged in the gri-framejust the nsame as theYA ordinary knives. I also make the third, eighth, thirteenth, and veighteenth rows ofhooks doubleheaded, in themanner illustratedat'Fig. 3. As willbe seen, there are two hookson each wire, and the one is turned to thegoneside the same as the other ordinaryv hooks, while the other is turnedto'the opposite side. In Fig. 3, l is the one hook, and 2 the other hook, whilej is the ordinary knife, and j the special knife. I also provide .a special twilling-bar k6, which is located between the second and third bars (see Fig. 2) and is retracted like the others by a springp. y This bar is connected by meansj: preferably, Vof the two springs q to two of the ordinary grilf-knives.

i hasthree hooks to the` needle and thirty rows of ,fifty hooks, or tifr is a spring fitted on the cylinder-frame s and which can act upon the special bar k6.

Now if we take a five-hundred machine,five satin double scale, with twenty rows of fty hooks, it will be possible to obtain by the actual working principle of the common harness-power looms the satins as in the diagram Fig. 5, where the white spaces of the paper represent the ground, the part within the double line the ligure, the cross-hatched dots the binding in the ground, and the black dots the binding in the figure. represents lifts and o prevents, or vice versa, and the device of a cross within a circle clashing.

It will be seen from studying Figs. l, 2, and 4 (Fig. 4 shows the simple arrangement for five rows of hooks, while Figs. l and 2 show this arrangement repeated four times for the full twenty rows of hooks) that at the first shot the peg m will actuate twilling-bar k', and by means of the catches o and their long hooks u (shown in blackin Figs. l and 2) lift the fourth, ninth, fourteenth, and nineteenth rows of hooksf and prevent by means of the pins Z on the twilling-bar 7s shifting their knivesj the second, seventh, twelfth, and seventeeth rows of hooks from lifting. Likewise at the second shot the peg m2 actuates the twilling-bart2 and moves the catches 02 so as to lift the rst, sixth, eleventh, and sixteenth rows of hooks n and prevent the fifth, tenth, fifteenth, and twentieth rows from lifting by its pins Z2. At the third shot the pegs m3 m, which are similarly situated on the peg-cylinder so as to act simultaneously, and the bars 7.33 7a move the pins Z3 ZG and the knivesj for the double hooks and the special knives jjzjsj, also for these hooks and thereby lift the third, eighth, thirteenth, and eighteenth rows and also prevent the third, eighth, thirteenth, and eighteenth rows. At the fourth shot the peg m4 and bar 7a4 lifts the fth,tenth, fifteenth, and twentieth rows and prevents the first, sixth, eleventh, and sixteenth rows. At the fifth shot the peg m5 and bar /65 lifts the second, seventh, twelfth, and seventeeth rows and prevents the fourth, ninth, fourteenth, and nineteenth rows.

It will be seen, Figs. 2 and 4, that the twilling-bars 7c3 and k6 have no catches o on them, but are merely provided with pins Z3 Z, Fig. 4, for moving the ordinary knives j and the special knives j to 7'4 for the double hooksf.

In the third shot the lifting and preventing of numbers three, eight, thirteen, and eighteen being identical, and therefore clashing together, could not work, and in order that the third shot may work it is necessary to move aside the ordinary knives j of the third, eighth, thirteenth, and eighteenth rows of double hooks, so as to prevent the lifting of any of these hooks, which in the ordinary way would have been otherwise lifted through the perforations of the card. This movement of the knives j is effected bythe action of the bar 7a3. The pushing forward of the special knives j to j4 by the bar 7c causes these knives to move into the vertical position and catch the rear heads of those double hooksf which are pushed back by the non-perforated parts of the card. As a consequence the hooks which are not lifted in the third, eighth, thirteenth, and eighteenth rows will make the binding in the figure, andlifting where there is no figure will operate the binding in the ground.

Fig. 3 explains the action of the knives and hooks. The ordinary hook l of the hook f can be caught by the ordinary knife j unless when this knife is pushed forward, (see dotted lines,) while the eXtra hook 2 is only caught on the special knife ,7" when this knife is pushed forward by its bar k6 and the hook f pushed back by the needle (Z. (See dotted lines.)

The springs q, attached to the griff-knives j and the bar 7s, exert when the griff-knives are moved by bar 7a3 a sufficient tension on the bar k6 to cause it to move forward at the time of lifting and force the specialknives to raise up those double-headed hooks pushed back by the card vertically whenclear of the other hooks. The forward movement of the bar 7a is checked and regulated by the spring lr.

To get the perfect binding all around as per Fig. 5 for the double scale or two hooks to the needle and two shots to the card, the designs or figures require to be painted on a number of five ends or threads in the vertical or horizontal ways or on an even number of threads and shots for a two-and-a-half-fold scale or two hooks to the first needle and three hooks to the second needle, and so on, and shot the same way two and three alternately and will give a machine of twenty-five rows of fifty, or twelve hundred and fifty hooks. For a fivefold scale of five hooks to the needle, however the pattern may be painted, it will make a perfect cloth same as a four-fold scale, with eight in ground and eight in figure.

In Fig. 6 an arrangement is shown for satins of seven and in Fig. 7 for -satins of nine. In the seven satin the clashing will occur at the fourth shot and in the nine satin at the fifth shot. The arrangement is the saine as with the five satin.

In Fig. 8 I have shown an arrangement for a satin of eight. Being an even satin, there is no trouble in the working. Four hundreds or double scale, sixteen rows of fifty, or eight hundred hooks.

By this operationa ground of three and one diagonal twill and a satin of eight in figure, or vice versa, will be obtained, and other combinations, as plain or taffetas ground one and one and eight satin or diagonal in figure or design, and vice versa, and many other armures or bindings may be obtained by changing twilling-bars and peg-cylinder.

By a similar combination tothe above satin 0f twelve a satin of eight in ground and twelve in figure, or vice versa, can be obtained, and also other combinations, as in the eight and eight machines.

The method of working will be readily understood from the examples given, and it will also be seen that for certain designs the loom will require to be altered so that the special double hooks and clashing knives may be at the correct places. Thus in the five-satin the third shot is the clashing shot, while in the seven-satin the fourth shot is the clashing one. v

The invention can of course be employed in silk and other weaving, as well as for linen damask fabrics. The invention of the eight and eight machines, Fig. 8, two, four, and even eight'fold scale are of the greatest advantage to silk, cotton, and woolen manufacturers, as large patterns perfectly bound'all around and making the most perfect fabrics can be obtained.
